4. what is the value of x?
Eva8 [605]

Answer:

4. 21

5.120

Step-by-step explanation:

(the answer for #4

I added 5x+15 and 3x-3

and got

8x+12

and because we needed to find the value of x, l did this

8x+12=180

because interior consecutive angles equal 180

and I got 21

(answer for 5)

I then plugged 21 into 5x+15 because angle 1 is equal to it

5(21)+15

I got 120

Suppose that a group of 10 students are to be assigned to four dorm rooms: a single, a double, a triple and a quad. How many way
Nesterboy [21]

Answer:

Total number of ways to select all sstudent to make assignment = 10×36×70×1 = 25200

Step-by-step explanation:

We have given number of students = 10

These 10 students are assigned to four dorm rooms a single, a double, a triple and a quad

So number of ways to assigned single student =^{10}C_1=\frac{10!}{1!9!}=10\\

Now left student = 10 -1 = 9

So number of ways to assigned double student =^{9}C_2=\frac{9!}{2!7!}=36

Now left student = 9-2 = 7

So number of ways to assigned triple student =^{7}C_3=\frac{7!}{2!4!}==70

Now left student = 7 - 3 = 4

So number of ways to assigned quad student =^{4}C_4=\frac{4!}{4!0!}=1

So total number of ways to select all sstudent to make assignment = 10×36×70×1 = 25200
